DISH-WASHER.

T0 at; 'wlwm it may concern:

Be it known that I, ARTHUR D. BUSH, a

citizen of the United States, and a resident of Olivet, in the-county of Eaton and State of Michigan, have invented a new and Improved Dish-Washer, of which the following 1s a full, clear, and exact description.

y invention relates to an automatic dish- Washing machine. The object thereof is. to provide a simple, sanitary and inexpensive will rinse dishes. to be washed, Wash them with a boiling, cleansing remove the cleansing solution, and deliver the so-cleaned dishes.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed. In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views. I

Figure 1 is a longitudinal section of a preferred embodiment of my dish-washing machine;

Fig. 2 is a fragmentary, horizontal section on line 22, Fig. 1;

Fig. 3 is a vertical cross section on line 3 -3, Fig. 1; 4 Fig. 4 is a similar section on line 4-4,

5 5, Fig. 1; I

Fig. 6 is an enlarged, fragmentary sectional view through the tank for the cleansing solution and showing the flashing tube inelevation; and v Fig. 7 is a horizontal cross seBc tion through 1g. 6. Referring to the .drawings, 8 is a. casing having transverse partitions 9 spaced from the top of the casing and sub-dividing the lower part of the easing into successive com- Fig. 5 is a vertical cross section on line partments 10, 11, 12,13 and 14:. The compartment 10 receives a water motor 15 to be actuated by the flow of water which is utilized in the machine for cleansing purposes.- Other motive-power means can be used if so desired, but this is a'preferable form.

is provided with extensions 16 forming tables at the level of the partitions 9. Each of said tables is preferably provided with a snrface formed of rollers 17 to facilitate the movement of the dishes placed upon the Sim face. The feeding table 16 preferably slopes toward the casing so as to facilitate the movement of the dishes placed upon the surface into the casing, while the delivery'table slopes from the casing to facilitate the movement-of the casing.

Cooperating with the surface 17 of the tables is a conveyer 18 extending between said tables over the compartments in the dishes comingout of the casing. Said conveyer is preferably formed of a' plurality of rollers 19 rotatably mount ed in a frame 20 extending over the tables 16. Each of the rollers is provided with. a gear 21 in mesh with a screw 22 extending longitudinally of the conveyor and adapted motor 15 through the medium of any suitable transmission 23 provided therebetween. The rollers 19 have the central art thereof removed to ofl'er a greater cearance.

In register with the clearance above the compartment 10 is a sprinkler 24 leading to a main supply 25. The connection between the sprinkler and the main is beyond'thc In addition to the main sprinkler 24, sprinklers 26 branch out from the sprinkler 24, the saidsprinklers 26 being located at suitable intervals so as to register with the'spaces between the rollers 19. These sprinklers will rinse the'dishes carried by the conveyerwith cold water. The compartment 11 hasin the clearance, formed by the rollers'l9 a sprinkler 27- similar to the sprinkler 24. and having branches 28 therefrom similar to the branches 26. The sprinkler 27 is also connected to the main but the medium of a heating coil 29 located in the chamberll above a heat-supplying device 30, which is preferably a gas burner. The sprinklers 27 and 28 will supthe dishes moving above the compartment 11.

The compartments 10 and 11 are provided with a common roof 31 located below the sprinklers and converging toward the partition between the compartments. A drain the liquid supplied above said compartment.

Flashing tubes 36 are interposed between the burner and the tank 34. Liquidis supplied to said flashing tubes 36 by a conduit 37 extending from the bottom of-the tank 34, said flashing tubes having ejecting ends- 38 passing through the bottom of the tank and extending substantially to the upper level thereof so as to be normally about half an inch below the liquid level in the tank. The portions of the flashing tubes above the burner have their heating area increased without materially increasing their cross section, thereby exposing a large surface of the tube 36 to the action of heat coming from the burner and thereby. generating steam rapidly in the enlarged portion of the tubes, the generated steam causing a violent eruption of the-cleansing solution from the tank 34. The cleansing solution within the tank may beof any suitable composition according to the character of the dishes to be cleaned. The heat supplied to the flashing tubes will also supply heat to the tank 34,

thereby maintaining thecleansing solution at a high temperature,

The compartment 13 is in communication with the compartments 11 and 12 to receive the gases of combustion therefrom and diarect the same out. from the casingthrough a conduit 39. If desired, special flues may be provided from the compartments 11 and 12 to the compartment 13. A roof 40 is provided at the top of said compartments which slopes downwardly and toward the tank 34 to convey thereinto any liquid that may fall upon said roof. Located above said roof-40 is a tube 41 adapted to supply a single spray for washing off the major portion of the cleansing substance .that remains on the dishes. This liquid will be carried off by the roof'40 into the tank 34 for which an overflow 42 is provided leading to the outlet 33. The tube 41 forms an extension of a sprinkler 43 located above the compartment 14 and connected to the main 25 by a heating coil 44 which is heated by a gas burner 45, both the coil and burner being provided within the compartment 14. roof 46 is provided over the compartment 14 below the sprinkler 43, the roof sloping toward the partition 9 whereat a drain 47 is provided connecting the roof and the outlet 33. The sprinkler 43 is adapted to deliver boiling water so as to easily wash the wardly washingcleanses the dishes thoroughly from whatever cleansing solution may remain passing thereabove. This latter thereupon, and the dishes are delivered thoroughly clean to the adjacent table 16.

A section 48 of the compartment 8 which surrounds the conveyer is preferably narrower than the casing, and is detachable. Its width preferably slightly'less than that of the conveyer. It is made detachable from the main part of the casing 8 to facilitate its cleansing and also to facilitate the inspection of the most chine. Preferably one. side of. the casing section 48 is rendered transparent, as shown at 49, to facilitate the inspection of the operation of may be observed.

While I have described the principle of operation, together with the device which I now consider to thereof, Idesire'to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the appended claims I claim.
